Pain is infl uenced by multiple factors including personal experience, psychological, sociocultural and situational factors. Failure to recognise pain will lead to poor patient management and deleterious effect on the patients wellbeing. Assessing pain in paediatric and cognitively compromised patients remains a challenge. Pain assessment in these groups of patients depends on the observers assessment and studies have shown the discrepancy between the observers assessment and patients verbal report. A specifi c and accurate tool is required to assist in the pain assessment. Although there are assessment tools available using behaviour scoring system and physiological indicators, none of the tool demonstrates its superiority than the others. Biochemical indicators such as stress hormones are frequently measured and used in con-junction with verbal reports; however they are non specifi c to pain and are increased in infl ammation, haemodynamic and emotional changes. The association between immunological indicators e.g. IL-1 , IL-6, IL- 8 and clinical pain has been shown, however; the defi nite correlation of the changes in the indicators and the level of pain is still unclear and may require further investigation.
Introduction: The aim of this study was to determine the effects of gamat extract on pain behaviour and Fos like immunoreactivity (FLI) expression in the ventral posterolateral thalamus using the acute pain model. Materials & Methods: Fourteen Sprague-Dawley male rats (220-300 gram) were given intraplantar injection of 0.05ml formalin (1%) followed by intraperitoneal administration of either 4 mg/kg gamat extracts (Holothuria spp.) or saline (control). Behavioural changes were observed and rats were sacrificed 2 hours post-formalin injection. Immunohistochemistry testing was done on the brain sections. FLI was examined using a light microscope attached to an image analyser. The behaviour and FLI data were analysed using repeated measure analysis of variance and independent t-test respectively. Significance level was taken as p
